Lab-Grown Diamond Engagement Ring

Imagine the gentle curve of a marquise diamond catching the soft morning light, its elongated silhouette echoing the quiet poetry of a Brooklyn sunrise. This semi-set solitaire invites you to choose a 7 x 3.5 mm marquise stone, whose tapered points and graceful length lend a subtle drama to the finger.

Crafted in warm 18K rose gold, the mounting’s delicate prongs cradle the stone with precision, while the smooth white gold band offers a cool contrast and a comfortable fit for daily wear. The low-profile setting ensures the ring sits close to the hand, making it glove-friendly and ideal for stacking with complementary bands.

Each piece is meticulously finished in our Williamsburg studio, where expert jewelers inspect every detail to balance elegance with durability. The lab-grown diamond option reflects a commitment to ethical sourcing and environmental mindfulness without compromising brilliance.

This design suits those who appreciate refined romance and a distinctive silhouette that elongates the hand. Its slender proportions harmonize with a variety of finger shapes and sizes, offering a graceful presence without overwhelming.

Should you need resizing or prefer a custom stone cut, our Brooklyn studio welcomes your vision with thoughtful guidance and a pressure-free experience.
